ResiDex is loaded with hundreds of reports. If you are a ResiDex user with many roles, you will have access to many reports. If you have limited roles, the report list will contain fewer reports. If someone suggests using a certain report and you don't see the report, it is likely you are missing the ResiDex Staff Role required to view the report.
Any person who can see the report name, will be able to find information on what role is required to run the report.
